Review on Enhance Aquarium CO2 Levels with AQUATEK 3-in-1 Diffuser & Bubble Counter (Large) by Ashley Jones

I've tried several CO2 diffusers for my 75 gallon freshwater aquarium, but others just haven't worked consistently. Other diffusers also required either an additional inert check valve in the CO2 line and/or a separate bubble counter. The resulting bubbles weren't as tiny as with the Aquatek. The Aquatek 3-in-1 diffuser has a non-return valve built into the bubble counter/atomizer, allowing for the use of only one length of tubing and evenly dispersing the smallest bubbles in the water. The suction cup really works due to its size compared to the diffuser. I connected a 2" piece of rigid tubing directly to the Aquatek which was then connected to a silicone tubing CO2 line, although this was not essential for proper function. This is as a precaution against twisting the flexible cord at the bottom end of the cone when larger fish bump into the Aquatek I have found that this 3 in 1 diffuser is made from thicker plastic than other diffuser/bubble counters and is very easy to clean thanks to the large screw cap which requires no tools It comes in two sizes and is reasonably priced considering it does three things I highly recommend the Aquatek 3-in-1.
